LOCK FOR FIRE-ARMS.

SPECIFICATION forming part of Letters Patent No. 351,262, dated October19, 1886. Application filed hlareh 9, 1386. Serial No. 194.511. (Nomodel.) kPatented in Belgium October 30, 1885, No. 70,619.

To @ZZ whom, t may concern:

Beit known that I, Josnrrr GoL'rs'rErN, a resident of Liege, Kingdom otBelgium, have invented an Improvement in Fire-Arms, (for one portiononly of which I have obtained Letters Patent in Belgium, dated October30, 1885, numbered 70,679,) of which the following is a completespecification, reference being had to the accompanying drawings,inwhich- Figures 1, 2, and 3 represent side views, partly in section, ofthose parts of a firearm to which my invention relates. Fig. 4 is asimilar view of a modification of the same.

This invention :relates to an improvement in the connection of themainspring of a tire-arm with the hammer and with other parts, by whichits action is modified from time to time, the object being, principally,to cause the said inainspring to automatically bri-ng the hammer to afull-cock and hold it there at all times, except while the user isaiming and ring.

The invention consists, principally, in causing both arms of Jthemainspring to act on the hammer alternately, and in combining it withmeans for controlling its several actions upon the hammer.

The invention is applicable to all kinds of tire-arms--such as ritles,Shotguns, revolvers, and the like-and may be usedon fire-arms havingtheir hammers exposed, and also on those whose hammers are entirelyconcealed from View. In the drawings the latter class of arms alone isrepresented.

In these drawings, A represents the breechpiece of the firearm, and Lthe firing-pin.

B is a hammer, pivoted as usual, and connected with the upper wing, a,ot' the mainspring C by a link, Z). The lower wing, d, is adapted torest on the shank e of the hammer. The wing c has a tendency to throwthe hammer B against the iiring-pin, as in Fig. 3, and the wing d has atendency to draw the hammer B away from the firing-pin, as in Figs. 1and 2.

In the breech-piece A is pivoted,atf,a lever, D, which connects by alink, g, Fig. 3, with the lower wing, d, of the mainspring C. The link gcan be dispensed with, as in Fig. 4, where a friction-roller, gi, isshown as interposed between the parts D and d. The lever D is at hjointed or otherwiseeonnected to a hand-piece, E, which at its rearportion connects with a sliding pin, F, that enters a socket in thestock or breech'piece A.

G isa trigger, engaging the hammer in the ordinary manner, H thetrigger-plate, and M the guard.

By the act of iiring the hammer is thrown against the iiringpin L, as inFig. 3, and immediately upon the hand-piece E being released the lowerpart or wing, d, of the mainspring presses or crowds thelever Ddownwardly, (see Fig. 1,) and by its contact with the shank e of thehammer throws the latter to thc position of full-cock, in which it islocked by the contact of the lever D with the trigger G. The parts arenow in the position shown in Fig. 1, and remain in this position untilaim i's taken. It will be seen from Fig. 1 that the pin] is in thisposition drawn partly out of its socket. By taking the gun in hand anddrawing it against the shoulder the manipulator presses with the righthand on the vhand-piece E, drawing the same backward into t-he positionwhich is shown in Fig. 2. By this act the lever D is turned on itspivot, so that it will raise the lower wing or part, d, of themainspring oft' the hammer. The hammer is now only held by the trigger,and only connected with the upper wing or part, u, of the mainspring,which has a tendency to throw it against the ring-pin. The arm is nowready for the discharge, which takes place immediately the trigger Gr istouched, whereupon the hammer is thrown forward, as in Fig. 3. As soonas the manipulator ceases pressing the hand-piece E backward the lowerwing of the spring d, which now bears on the shank ofthe hammer, willthrow the latter' into the position of full-cock, as in Fig. 1. In orderto enable this to be done, the lower wing or part, d, of the spring ismade much more powerful than the upper wing or part, a, because theresistance of the part a must be overcome by the part d in order tobring the hammer from the position shown in Fig. 3 into that shown inFig. 4.

Instead of making the parts a d as shown, they may be indicated in Fig.4.

in one piece, made in two pieces, as

IOO

1. In a 'fire-arm, the Combination of the lever D with the spring d andtrigger G, and hammer B, said spring being placed behind the hammer andover said lever, so that it Will be G, hand-piece E on lev'er D, andguide-rod F onhand-pieoe E, all arranged so that the mainspring isstrained by the action of the stronger portion of the hand on thehand-piece E, leav- 5 strained by the action of the hand upon the l ingthe trigger-linger free to perform thelightx lever D, as specified.

2. The combination of the hammer B with the link Z), spring C, havingtwo Wings, a d, the link b joining the hammer to the Wing ci, To leverD, connecting with the Wing cl, trigger er action of pulling thetrigger.
